| GO:0004888 | transmembrane signaling receptor activity | molecular_function | Combining with an extracellular or intracellular signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity or state as part of signal transduction. [GOC:go_curators, Wikipedia:Transmembrane_receptor] |
| GO:0007165 | signal transduction | biological_process | The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. [GOC:go_curators, GOC:mtg_signaling_feb11] |
| GO:0008285 | negative regulation of cell population proliferation | biological_process | Any process that stops, prevents or reduces the rate or extent of cell proliferation. [GOC:go_curators] |
| GO:0032759 | positive regulation of TRAIL production | biological_process | Any process that activates or increases the frequency, rate, or extent of TRAIL production. [GOC:mah] |
| GO:0032760 | positive regulation of tumor necrosis factor production | biological_process | Any process that activates or increases the frequency, rate or extent of tumor necrosis factor production. [GO_REF:0000058, GOC:TermGenie, PMID:10891884, PMID:15560120] |
| GO:0043065 | positive regulation of apoptotic process | biological_process | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. [GOC:jl, GOC:mtg_apoptosis] |
| GO:0071260 | cellular response to mechanical stimulus | biological_process | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a mechanical stimulus. [GOC:mah] |
| GO:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| GO:0005737 | cytoplasm | cellular_component | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684] |
| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| GO:0070062 | extracellular exosome | cellular_component | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
